IDL SPEDAS had the same issue: it was constructing some variable names with double suffixes, in a block of code that now appears to be unnecessary. The pitch angle variables are now in different CDFs, with datatype des-momsaux and dis-momsaux. Support has been added for the new data types, the bad/unnecessary variable checks have been deleted, and the pitch angle variables can now be loaded and plotted when available in the momsaux files.
First noticed for pyspedas, see: https://github.com/spedas/pyspedas/issues/995
